Tddld'w'iiom may concern:

3e it known that we, Jerma n KREME- NEZKY and Josnr Jnntixnk, both subjects of the Emperor of Austria-Hungary, and residents of Vienna, Empire of Austria-Hungary, have invented certain new and useful Improvements in Machines for Producing Beads-on Glass Rods; and We (lo-hereby de clare the following to be afull,- clear, and

exact description of the invention,- such as will enable others skilled in the art to which it"a'ppertains'to make and use the some.

-This invention relates to a machine for producing beads on glass rods, more particularly on such glass rods as are used in the supporting." frames for metal filaments of electrici'nii'ndescent lamps; the said beadsbeing prpduced by heating and upset ting the rods arrangedin groups in frames all the rods of a group'undergoing the same operation sinru-ltan'eously- According to the present invention the glass rods are clamped in a frame rotated step by step, the said frame consisting of two parallel wheels rotating together; one

of these wheels carries the chucks for holding in position the glass rods While the other Wheel carries upsetting frames opposite the chucks, movable in a direction parallel to the axis of the wheels. In order to secure a thorough and uniform heating of those parts of the glass rods which are to be upset for obtaining the beads, the chucks are revolved-around the longitudinal axis of the glass rods while they are in the various working positions.

In the drawings Figure 1 is a plan view of those parts of a machine embodying this invention which are required for understanding the latter. Figs. 2, 3 and 4 are radial sections of Fig. 1 on the lines 0 A,

O B and O- C respectively.

In a Wheel or disk 1- a member of equi-- distant groups of chucks is mounted, each such group comprising a plurality of individual chucks 2 in which the glass rods 3 are secured by hand so as" to be normal to the plane of the Wheel 1. A seeond wheel 11 parallel and clutched to the wheel 1 so as to rhtate with this latter Wheel'carries upset ting frames 12 opposite the groups of chucks and adapted to be reciprocate'd ina direction to its plans.

The meeemems the wheeleany convenient-manner, thearrangement bemg preferablysuch that on depressing the treadle first the upsetting frames are raised and then released after the two Wheels have started forward through the distance between two adjacent groups of chucks. 'Upon raisingthe upsetting frames the heated ends of the glassrods are upset forming beads. At the same time the pawl 17 by depression of the treadle is brought out of engagement with the spoke of the wheel 11, and the wheel has begun to rotate; The pawl 1 7 thenclears the spokeduri-ng'the rotation of the'wheel and the trea'dle is releasedg-lowering the upsetting frame out of action and returning the pawl-to its normal position ready for engagement with the next spoke of the wheel.

The glass rods are secured by hand in the chucks 2 of the groups occupying the position A Fig. 2-. After the rods have been secured the attendant depresses the" treadle whereby the Wheels 1 and 11 are turned through the distance between two adjacent groups of chucks thus bringing the group which had previously occupiedthe position A into the position l3 Figs. 1 and 3. In this position in Which parts of the glass rods 3 near their ends are opposite burners 5 the rods together with their chucks are revolved around the longitudinal axes of the rods by means of a pinion 6 jour'naled in the Wheel land coming into engagement with a pinion 7 when the group of chucks arrives in the position B. The pinion 7 is continuously rotated by a pinion 9 loose on the shaft 8 of the wheel 1. The pinion 6 drives pinions 10 on the chucks. All pinions 10 of a group of chucksniesh with their neighboring pinions.

While thegroup of rods in the position B is heated by the flames of the burners the attendant removes the finished rods already provided with beads from the chucks. While this is being done the glass rods of the group in the position B have been softened; near their top ends. The "attendant then again depresses the treadle whereby as will be readily seen from Fig. 3 the up- ,set'ting frame 12 occupying the posit1on'- B is raised-.- This-upsetting frame carries pins 13. in'liho' with the glsee feds held iit ting frames are preferably derived from a single treadle' lever 1-8 indicated in Fig. 3 in chuchs which are preferably rcvoived with the some angular velocity end in the some direction as the rods by any suitable gearing. upse'bting frame raised so that its strike against the bottom. ends of the glass and force them upward whereby the softened parts near the hop end of the ere cpsei so as to form heads. W hen this has been done and the up setting frame has been moved away from the glass rode the Wheels 1 and 11 are turned forward through the distance between two adjacent groups so that "she group which had. previoui iiy occupied the position :8 now comes into the position C Figs. 1 and a: in which the chucks and also the pins 13 are revolved as above described with reference to the position -33 and. in which the bottom ends of the glass rods are opposite burners and are heated by the flames of the latter. On next depressing the :treadie she no setting frame may he raised. in the some way as described with reference to the position B so that its pins 13 upset the softened bottom endsof the gloss rods Wherehy these ends are formed into heads. Ur instead of being directiyrsised by depressing the treshe the upsetting frame 12 may he raised oy the movement of the Wheels 1 11 caused by G )ressing the treeciie for bring ii'ig these Wheels from the position G into the position D. For JiiiS purpose, projection provided on the upsetting frame which passes over a cam surface 16 fixed in the frame of the machine" In the position D the ghiss ro is do not undergo any further operation but left to themselves for cooling. The next movement of the Wheels 1 snci 11 carries the group of checks from she position B into the position the finished glass rods are taken one of the chucks by hand. and. free ones inserted, whereupon the series of co erocions is repeated with these fresh rods. For correctly iiiiiiiiiing the forward. move ment of the Wi168 f3 1 and 13. a spring are coated pawl 1'? is provided in the frame of the machine against which strike suiczi *ie stops for instance the spokes of one of ch wheels 1L Us depressing the treai ciie this pewi is brought out of engogemens with the above mentioned stop before the Wheeis )egin to more. instead of being operated directly by the treucile as above indicated the Wheels 1 and 11 might be ecfiueteci by a Weight or spring rcieased on depressing the erectile, such Weight being raised or spring being WOLHlCi up by the pinion f) or other continuously moving part of the machine whiie the Wheels are at rest, or the arrangement might be en 11 that he treaciie only raises the up e ting frame in the position and throws out of engagement the pawl 17, While the attendant moves the Wheeis l and 11 by head. this case the attendant sfher having depressed. she treeciie has so horn the Wheels by hand; imniedieieiy after hov ing started them the attendant inusi; release the trendie order that the pawl 1? may stop the movement oi the Wheels in their correct position he machine above described permits of monuiectoring glass rods for the fiien'ienis supporting frames of electric incandescent himps with great nicety avoiding the oi? breaking or distorting ithe rods, because the blanks may be inserted with great era:- acbness into the chucks in. which they are their safe-1y heici.

By arranging the blanks in groups subjecting all the blanks of o group to -:Zhe successive operations siniuitaneocsiy the cime required for heetinp; the blanks of, different points may he utilized for removing finished blanks and inserting fresh ones and the attendant co select the speed of Workot Wiii to suit the conditions existing at any time, withe s-i, having "so adjust any port Whatever, whereby Egress eiiiciency anti Working under the roost ierorohie conditions are secured.
